NADP(H) allosterically regulates the interaction between ferredoxin and ferredoxin‐NADP+ reductase [PDF]
FEBS Open Bio, 2019 Ferredoxin‐NADP+ reductase (FNR) in plants receives electrons from ferredoxin (Fd) at the end of the photosynthetic electron transfer chain and converts NADP+ to NADPH. The interaction between Fd and FNR in plants was previously shown to be attenuated by

NADP(H)-dependent biocatalysis without adding NADP(H)
Proceedings of the National Academy of Sciences, 2022 Isocitrate dehydrogenase 1 (IDH1) naturally copurifies and crystallizes in a resting state with a molecule of its exchangeable cofactor, NADP + /NADPH, bound in each monomer of the homodimer. We report electrochemical studies with IDH1 that exploit this property to reveal the massive advantage of nanoconfinement to ...

Identification and evolution of C4 photosynthetic pathway genes in plants
BMC Plant Biology, 2020 Background NADP-malic enzyme (NAPD-ME), and pyruvate orthophosphate dikinase (PPDK) are important enzymes that participate in C4 photosynthesis. However, the evolutionary history and forces driving evolution of these genes in C4 plants are not completely

Antioxidants, 2022 Plastidic ferredoxin-NADP+ reductase (FNR) transfers two electrons from two ferredoxin or flavodoxin molecules to NADP+, generating NADPH. The forces holding the Anabaena FNR:NADP+ complex were analyzed by dynamic force spectroscopy, using WT FNR and ...

NADP+ reduction by human lymphocytes [PDF]
Clinical and Experimental Immunology, 1990 SUMMARY The hexose monophosphate shunt (HMPS) is known to be responsible for the reduction of NADP+ by lymphocytes. We tried to find other enzymatic systems that might provide the lymphocytes with NADPH. By measuring the absorbance at 340 nm we noted that the addition of NADP+ to a preparation of disrupted lymphocytes resulted in the ...

Adaptation responses in C4 photosynthesis of sweet maize (Zea mays L.) exposed to nicosulfuron
Ecotoxicology and Environmental Safety, 2021 Nicosulfuron is an ingredient in photosynthesis-inhibiting herbicides and has been widely used in corn post-emergence weed control. In the current study, a pair of sister lines, HK301 (nicosulfuron-tolerence, NT) and HK320 (nicosulfuron-sensitive, NS ...

Bio-Protocol, 2014 A recent study demonstrated that cytosolic phosphoenolpyruvate carboxykinase (PEPCK) and NADP-malic enzyme (NADP-ME) have an important role in malate metabolism during fruit ripening (Osorio et al., 2013). PEPCK catalyze the ATP-dependent decarboxylation

Cytosolic NADP-isocitrate dehydrogenase in Arabidopsis leaves and roots
Biologia Plantarum, 2012 NADP-dependent isocitrate dehydrogenase (NADP-ICDH) catalyses the production of NADPH, which is an essential component in the cellular homeostasis. In Arabidopsis, the kinetic parameters (K m and V max) of cytosolic NADP-ICDH were different in leaves and
